Acetyl Tetrapeptide-3

This biometic peptide is designed to support hair growth.

According to a manufacturer, it stimulates hair growth by:

• strengthening the extracellular matrix in the scalp
• boosting key parts to the extracellular matrix, such as collagen type III
• boosting laminins to create stronger hair anchoring

The manufacturer has found combining this ingredient with red clover extract (Capixyl) boosted benefits. Not only does it enforce the scalp's extracellular matrix, it also inhibits the enzyme that creates DHT, a hormone that leads to hair loss.

While this ingredient is promising, more research is still needed to confirm its full effectiveness.
